The size of the antenna is 0.8 mm × 30 mm × 34 mm. A circular arc shaped T patch is used as the radiating element of the antenna, and a notched band is realized by embedding the L shaped slot on the radiating patch. The simulation results show that the bandwidth of the antenna is 2.9 - 10.8 GHz with the notched band of 3.3 - 3.7 GHz; the average gain of the antenna is about 4.0 dBi; and it has a stable quasi omnidirectional radiation characteristic. The antenna can meet the application requirements of a variety of ultra wideband communication systems.
